Mail Survey

The mail survey is a research method which Nikkei Research adopts as frequently as the Internet survey. The annual number of surveys and handled samples are as large as those of the Internet survey. The number of cases in which a mail survey is utilized has been increasing to conduct a customer survey after the enforcement of the Private Information Protection Law.

Nikkei Research conducts and manages surveys under the management system to handle the mail survey efficiently and safely enough to ensure the protection of private information.

Respondents' private information is not included in the questionnaire to prevent an individual from being identified from the questionnaire.

If it is necessary to check whether a questionnaire is returned from individual samples and specific targets, Nikkei Research manages the situation based on IDs, using barcodes.

Nikkei Research has introduced the reward sticker as a means of giving respondents rewards. We ask respondents to return the reward sticker on which the delivery address for the reward is written together with the completed questionnaire. When Nikkei Research sends the reward, the sticker is used as an address label to be put on the envelope. In this way, no respondents' private information is left in Nikkei Research.
